Abstract: An image reading apparatus includes a flatbed image reading unit, an ADF image reading unit, a storage unit, and a control unit, wherein the control unit includes a flatbed image-reading control unit that controls the flatbed image reading unit to read an image of a read-condition setting sheet, and stores the image of the read-condition setting sheet in the storage unit, a read-condition determining unit that determines a read condition from the image of the read-condition setting sheet read by the flatbed image-reading control unit, a read-condition setting unit that sets a read condition for a document to be read by the ADF image reading unit according to the read condition determined by the read-condition determining unit, and an ADF image-reading control unit that controls the ADF image reading unit to read an image of the document according to the read condition set by the read-condition setting unit, and stores the image of the document in the storage unit.

Abstract: A sheet feeding apparatus includes a sending element of an ultrasonic sensor for outputting ultrasonic waves, a drive circuit for supplying the sending element of the ultrasonic sensor with a drive signal for driving the sending element, a receiving element of the ultrasonic sensor disposed opposite the sending element of the ultrasonic sensor across a sheet transfer path in the sheet feeding apparatus, and for receiving the ultrasonic waves, a setting unit for setting a threshold for the detection of transfer of the plurality of paper sheets by using the output of the receiving element of the ultrasonic sensor at the time of stopping of the output of the sending element of the ultrasonic sensor as a basic value, and a detection unit for detecting transfer of the plurality of paper sheets by comparing the output of the receiving element of the ultrasonic sensor with the threshold.

Abstract: A jukebox apparatus including a magazine, a drive unit, a carriage for conveying a disk between the magazine and the drive unit, and a temporary storage unit movable between a transfer position in front of the drive unit and an escape position. The carriage has gripping arms, pinch rollers, and a pushing arm for transferring the disk. A control unit is provided to carry out a retry of transferring the disk by displacing the carriage when the disk is not transferred. The pushing time of the pushing arm can be changed by a retry of pushing the disk by the pushing arm. The temporary storage unit is normally monitored.
